Problem Description

Issue

Nightly AMP backups of my Valheim server are roughly 4x larger after the Valheim server updated to the latest patch. It seems to now be including newly patched files from the valheim_server_Data directory that I do not actually want to backup.

I’d like a configuration option to control which files are backed up (in my case, I only care about the “Saves” folder). A file glob or regex list would be sufficient. I see that it may be possible to do this with a custom template, but I believe that would require re-deploying the app.

Reproduction Steps

• Start a new Valheim server
• Configure nightly backups in AMP with the “smart backup” option (to exclude unnecessary files)
• Let server run for a few days (max backup size around 50MB)
• Update Valheim server to a newer release (latest patch)
• Smart backups now include new content from the patch under valheim_server_Data. Backup sizes now 220MB+ each.

Backup Exclusions

Note: As of AMP 1.8 backup exclusions can be configured via the file manager GUI. Backup exclusion files allow you to specify files or folders to be excluded from backups. The file is always named .backupExclude and needs to be placed in each directory for which you wish exclusions to apply. If you place such a file in a directory, and that file is completely empty - that entire directory and all its contents will be ignored. If you want to ignore certain items, you simply list them. You can …

Thank you! I somehow missed this when searching.

One general piece of feedback: I’m sure it’s come up before, but it would be helpful to have these kinds of instructions combined into a structured wiki or README.md for easier referencing. Or, alternatively included in additional tooltips/help menus in the application. It’s a bit cumbersome to search the forums for each of these features.

Regardless, thank you for the quick reply. Cheers!

As you know, the search function in AMP is only partly helpful, since the search list is not dynamic and so a lot of more recent (as in, within the last 12-18 months…) KB articles do not show
